frxos is my little pet project. The goal is to get a very basic, but working, operating system up and running.

• Serial input/output
• Easy debugging
  • Press Pause to show current state (registers, stack, stack trace, disassembly etc.)
• Keyboard input
• Display output
• Hardware-based timer
• Memory management
• Basic shell
• Hard drive access
• User-space programs

To build, ensure that you have an i686-elf toolchain installed (precompiled binaries available here), the GRUB bootloader and make.

To build, run make all.

To run locally with QEMU, run run.sh (requires qemu-system-i386 in PATH) or run qemu-system-i386 -kernel frxos.elf.
